Reduce driveline vibration on lifted vehicles with this Heavy Duty Slip-Yoke Eliminator Kit for Jeep's NP231J transfer case. Transfer case tailshaft length is reduced by 6.5" on '97-'01 Wranglers and 4.25" on '88-'95 models resulting in improved driveline angles. Kit includes a redesigned transfer case mainshaft which is not only shorter but has an 18% larger spline diameter, a 54% increase in torque capacity.

Comments: The Advance Adapters SYE kit was relatively easy to install. I was a bit nervous because I'd never torn apart a transfer case before, but the install was so simple, I would love to do it again just for the hell of it.

Comments: I would HIGHLY recommend this. Even if you dont have a big lift, or at all, get this ASAP. It will get rid of driveline vibes and you wont have to worry about your driveline sliding out when it pops a U-joint and slamming onto the ground
